The engine misses. The RPM's vary without the throttle being moved.

Mechanic's Assistant: Sometimes things that you think will be really complicated end up being easy to fix. The Marine Mechanic I'm going to connect you with knows all the tricks and shortcuts. Tell me a bit more about what's going on so the Marine Mechanic can help you best.

The engine starts fine. When I accelerate the engine misses noticeably under load.

Mechanic's Assistant: Is there anything else important you think the Marine Mechanic should know?

This condition started after refueling. Could I have dirt clogging an injector? Water in the fuel?

Hello my name is ***** ***** am I speaking with? I read what you wrote but I do not see any kind of model information. What engine are you asking about? Do you have any kind of make, model # and serial # information?

Hi Bill. Is this a 2 stroke or 4 stoke? Carbureted or fuel injected? Optimax? Mercury outboards are cataloged by serial number, if you have that number handy that would be best, ***** ***** would tell you exactly what you have. Do you have that number available?
